What the study found

The authors define a new realization of the Yangian of gl n, a kind of algebraic structure, for any family of orthogonal polynomials. They also introduce a ternary Yangian for a ternary extension of a Lie algebra as a flat deformation of its current algebra.

Why the authors say this matters

The study suggests that this construction gives a broader way to build Yangian generators from families of polynomials or functions. The authors also indicate that the ternary Yangian extends the same algebraic framework to a ternary setting.

What the researchers tested

The researchers developed a new choice of generators for the Yangian of gl n and checked the RTT relation, a standard algebraic relation in this area, in the case of Dickson polynomials. They also describe similar constructions for families of functions satisfying certain recurrence relations, including q-Pochhammer symbols and Bessel functions.

What worked and what didn't

The new generators were shown to satisfy the RTT relation for Dickson polynomials. The abstract also states that similar constructions can be made for other families of functions with suitable recurrence relations, but it does not give detailed outcomes for those cases.

What to keep in mind

The abstract provides limited detail about proofs, examples, or the scope of the construction beyond the named families. It does not describe limitations or failures, so none can be stated from the available summary.

Key points

  • A new realization of the Yangian of gl n is defined for any family of orthogonal polynomials.

  • Similar constructions are stated for q-Pochhammer symbols and Bessel functions.
  • The authors introduce a ternary Yangian for a ternary extension of a Lie algebra.
  • The ternary Yangian is described as a flat deformation of a current algebra.
